What are the layout methods of precision stamping parts?
- Sampling of waste
Refers to other plates other than workpieces during the blanking process of precision stamping parts, including process waste and structural waste. All material contour lines are blanked, and there are process residuals between workpieces and workpieces and between workpieces and strips. Due to the blanking along the closed contour of the blanked part, the quality and die life of the blanked part will be relatively high.
2. Sampling with less waste
Precision stampings are cut or stamped along the contours of parts of the workpiece and have laps between the workpiece and the workpiece, and between the workpiece and the sides of the strip. The blanking of this method is only a part of the contour of the workpiece, which is affected by the quality of the cut strip, the positioning accuracy and the error. The quality of the blanking parts is slightly poor, but the material utilization rate can reach 70%~90%.
3. No waste layout
Precision stamping parts have no overlap between the blanking parts and the blanking parts, and between the blanking parts and the sides of the strip. In fact, the blanking parts are obtained by cutting the strip, and the material utilization rate can reach 85%-90%. However, this layout method will make the quality of the blanking parts slightly worse.
